Great post - may I ask how old are you ?
This world has definitely offered a lot for me over the past 20 years. I just had this conversation over beers with a really good friend that also partakes in this industry and we came up with some interest positives that I've listed below. I've certainly experienced some bad things, and I've heard stories from some ladies I've grown to close to that have opened up that make me want to cry, but for the most part, fairly positive.
Single in my 20's: Allowed me to realize I didn't have to stay in shitty relationships with women who were terrible matches for me to get access to sexual relief. This allowed me to qualify potential girlfriends and partners very fast and not get trapped in a relationship with someone I really didn't want. Not having the distraction/drama from a bad relationship let me concentrate on work too.
Married: I had an amazingly good time with my ex wife for years. We experimented together by meeting women we approached in this industry. Experienced all sorts of wonderful times.
Going through divorce: We left each other for reasons not having to do with sex or cheating. It was a painful time, and a lot of women from this industry made it bearable. I'm sure some of the moments I've that helped me through some sad times were manufactured by the Provider, and other moments were very real and genuine. Either way, it was helpful.
Single 2nd time around: See my comments about my 20's, the same concept still applied. The only difference is that I've been lucky to have stumbled my way into an excellent career and I found that I could afford dinner dates, weekend trips, etc. Which meant, I've had a lot of time to build a connection with the ladies I've seen which means I've developed great bedroom chemistry with some. In the case of two women, the bedroom part died out but a friendship blossomed, and both of those women I've been in touch with daily/weekly for nearly 10 years as actual platonic friends and we're involved in each others personal lives and no money and no sex has ever exchanged again
Married again: If you count sugar daddy sites as part of this industry, then here's the ultimate benefit....I met my current SO on it. What started out as an arrangement blossomed into something totally different which neither of us were expecting. And because I met her under these circumstances, I've been 100% myself from the start which I never even had with my first love/ex wife. It's amazingly freeing when you can talk to your wife and say "I can't get this look out of my mind! I might be developing a thing for red headed curvy women with freckles wearing penguin costume and green heels to peg me with a glass dildo while you watch... I think I want something like this one day" and she'll find a way to get this for me, even if it involves someone else. We have very firm rules in place for each other with the understanding that if these rules need to change, it's a very serious thing we need to bring up and discuss. She's a saver and frugal with money which has been amazing for me financially as well. We're discussing having children now.
I'm pretty sure I've provided some nice value to some ladies lives as well. Aside from the obvious, I've been told the advice I've given on life, money management, school, career, relationship, parenting, etc has been invaluable. I don't think its lip service either.
